Be it known that I, FRED I. GETTY, a citizen of the United States ofAmerica, residing at.

Springfield, in the county of Sangamon and State of Illinois, haveinvented certain new and useful Improvements in Chromatic-PrintingDevices, of which the following is a speciflcation.

My invention relates to improvements in chromatic printing devices, itsobject being to provide a practically operated self-inking block,adapted to be set in an ordinary form of type in the printing-press andto print in the color furnished by its own inking mechanism which, maybe entirely dierent from that furnished to the remainder of the form bythe inking rollers of the press. By the use of such a device anadvertisement or any other -lnatter may be printed in a newspaper, inany desired color, while the body of the paper is printed in black inthe ordinary manner. The matter thus printed incolor is evidently mademuch more noticeable than if it were printed in black and thus. securesa prominence which adds greatly to its attractiveness and value.

The invention, by means of which I have obtained this obj ect,is fully,described and explained in this specification and shown in theaccompanying drawings, in which-` Figure l is a top plan of a deviceembodying my invention. Fig. 2is a vertical section through the lineac-, Figs. 1 and 3, the view 'being in the direction indicated by thearrow, a, in each of said figures and the side wall, A, being removed toshow construction.

Fig. 3 is a vertical section through the line '-.z;', Figs. l and 2, theview being in the direction indicated by the arrow, a', Figs. l. and 2.Figa is a vertical section'through the line @c2-m2, Figs. l and 3, theView being in the direction indicated by the arrow, d, in

each of said gures and the printing-bars be-l ing in contact with theinking-pad of the device and not in position to print. Fig. 5 is a viewsimilar to that shown in Fig. 4, except that the printing-bars are inposition to print. Fig. 6 is a vertical section through the line ac3-w3,Fig. 1, and Fig. 7 is avertical section through the broken line :c4-m5,Fig. 1, the part x4 of the' line being through `the longi- Each of theside walls, A, is bored out or recessed from `end to end for thereception of a shaft, B, Figs. 2, and '7, reduced in size near itscenter and having its reduced portion encircled by a spring, S, one endof which is fastened in the shaft, while the other end enters the sidewall, the spring being so coiled and under such tension as to rotate theshaft in the direction indicated by the arrow thereon in Figs. 2, and 7.On each end of the shaft is formed a pinion, B', Figs. 2, and 3, of suchlength and so placed that a portion of it engages a rack,'C, on thecorresponding end of a vertically sliding plate, G, lying' in closecontact with the side wall of the box, while the remainder of it engagesa gear-wheel, B2, set in a recess in the corresponding end wall of thebox. Each of the'gear-wheels, B, is provided'with an arm, B3, Fig. 3,lying in a recess in the corresponding plate, A2; and as each of theshafts, B,'has a pinion at each of its ends, each of the two plates, C,C, is evidently forced upward by pressure, applied to both its ends, andeach of the four gearwheels B2, is rotated in a direction opposite tothat indicated by the arrow on the pinion B', in Fig. 3, the arms B3, ofthe gear-wheels being thereby pressed downward and normally held in theposi-tion shown in said iigure. Within the box, thus described,'lies avertically movable rectangular frame made up of end bars, D,'D, and sidebars, D', D',"

IOO

frame lie just within the plates, A2, of the end walls of the box, butare provided at their upper edges with horizontal flanges extendingoutward and resting normally upon the upper edges of the plates, A2.Suitable sockets are formed in the plates, A2, for the reception ofscrews, s, S, Figs. 3,and G,whose ends enter and engage the overhangingedges of the end bars, D, D, and springs, S', S', encircling the screwsand pressing downward against the heads thereof and upward against theends of the sockets tend to draw the frame, D, D', downward and hold thefianges of its end bars in close contact with the upper edges of theplates, A2. The ends of the arms, B3, of the gear-wheels, B2, lieimmediately under and in contact withthe flanges of the end bars, D, D,of the movable frame, as shown in Figs. 3, 4, and 5; and it is evidentfrom the foregoing explanations of the relations of the pinions, B',gear-wheels, B2, arms, B3, plates, C, and frame, D, D', that if theplates, C, be pressed downward with suf fcient force to overcome theresistance of the springs, S, S', the free ends of the arms, B3, must beraised and the frame, D, D', be pressed upward from the position, shownin Figs. 3, and 4, to that shown in Fig. 5.

Within the frame, D, D', are suspended a series of transverseprinting-bars, F, F, prefably prismoidal in form and provided with typeT, T, formed upon or attached to their faces, the type being of anydesired design and adapted to print any desired characters or symbols.Each of the printing-bars is provided at its ends with gudgeons,f, Fig.7, journaled in the end bars D' of the frame, and plates, f',corresponding in shape to the cross-section of the printing-bars, arefastened to the ends of the gndgeons and lie in recesses in the outerfaces of the end bars, D', of the frame (see Figs. 4, 5, and 7). Metalstrips, d, lie along the upper edges of the side bars, D', of the frameand across the ends of the printing-bars, and these strips are drawndownward by means of screws, s', setin sockets in the side bars, D', andencircled by springs which press downward upon the heads of the screwsas illustrated in Figs. 5, and 7. The printing-bars, F, and plates, f',as shown, are triangular and each of the plates is provided with aseries of pins, P, P, P, placed at the vertices of its three angles, allthe pins of each of the plates being within a corresponding opening inthe adjacent stationary plate, E. Each of the openings in the plates, E,is formed with inclined faces, O, O', in its upper and lower margins,respectively, and has also in its upper margin two horizontal faces, n,

fn, and its lower margin two similar faces, n', n', the two horizontalfaces in each margin of the opening being in the same line and onopposite sides of the inclined face, o or o'.

When the parts are all in their normal position, as shown in Figs. 4, 6,and 7, two of the pins, P, P, of each of the plates, f', lie in contactwith the horizontal faces, n', n', of the corresponding opening in theplate, E, and one of the faces of each of the printing-bars is thus heldin ahorizontal position and looks directly downward. In this positionall these horizontal faces of the printing-barsare in con tact with theupper surface of an inking-pad, X, Figs. 5, G, and 7 fastened to thebottom plate of the box, A, A', and the type upon these horizontal facesare thus supplied with ink and prepared for printing at the next opera-ltion of the device.

If now the plates, O, C, be pressed downward the frame, D, D', and theprinting-bars suspended invit must be pressed upward in the mannerhereinbefore explained; and in this upward movement, the pin, P, at theupper angle of each of the plates, f', must strike the inclined face, o,at the upper margin of the opening in which it lies and thus be movedlaterally along the margin of the opening until it reaches one of thehorizontal faces, n, n. This lateral movement of the pin, P, accompaniedby continuing upward movement of the frame, D, D', rotates each of theprinting-bars in such a way that atthe conclusion of the movement two ofthe pins P, P, on each of the plates, f', rest against the horizontalfaces, n, n, at the upper margin of the corresponding opening in theplate, E, thereby holding one of the faces of the printing-bar in ahorizontal position in which it looks directly upward. This position ofthe printing-bars is illustrated in Fig. 5 and when the parts are inthis position, if the plates, C, C, be allowed to move upward under theinfluence of the spring, S, the frame, D, D', must drop down to itsnormal position carrying the printing-bars with it. In this downwardmovement the pin, P, at the lower angle of each of the plates, f',strikes the inclined face, o', below it and moves laterally downwarduntil it reaches one of the horizontal faces, n', this lateral anddownward move ment being such as to rotate the printingbars, so that atthe close of the movement two of the pins, P, P, on each plate lie incontact with the faces, n', and the horizontal faces of all of theprinting-hars look downward in the manner, shown in Figs. 4, 6, and 7,and already described. It will be observed that the inclined faces, o',in the right-hand halfof Fig. 4 incline to the right while in theleft-hand half of the figure they incline to the left; and also that theinclined faces, o, in the righthand half of the figure, are at theright-hand side of the centers of the openings in the plate, E, while inthe left-hand half of the figure, they lie on the left side of thecenters of the respective openings. This arrangement rotates each of theprinting-bars step by step in one direction, the rotation of the bars inone half of the block being in one direction and that of the bars in theother half being in the opposite direction, although all of the barsmight be rotated in the same direction. W'hen the printing-bars are inthe position, shown in Figs. 4, and 6, each of the strips, d, is raised,butwhen the printing-bars begin to rotate in the upward movement of theframe, D, D', the downward pressure of the strips upon the printing-barsassists in the rotation and tends' to bring them speedily and positivelyinto the position, shown in Fig. 5. When the printing-bars reach theposition shown in Fig. 5, their horizontal upper faces lie substantiallyin the plane of the upper edges of the box, A, A', and the type uponthese surfaces are intended to be in the plane of the typeof a formresting on the same bed which supports the printing-block.- On the otherhand when the printing-bars are in the position, shown in Figs. 4, and6, they are suitably below the printing-face of the form and aretherefore out of reach of the inking-roller which supplies ink to thebody of the form.

In use the block, thus described and explained, may be locked withordinary type in a form resting on the reciprocating bed of any press inwhich the paper is carried and pressed upon the type by a rotatingcylinder. The printing-bars are in the position, shown in Figs. 4, 6,and 7, and the plates, C, C, projectabove the edges of the box, A, A'.As the form passes under the inking-rollers the faces of the ordinarytype are inked, but the type upon the printing-bars, F, are wholly belowthe inking-rollers and receive no ink from them the pressure of theyielding inking rollers upon the edges of the plate C, C, beinginsufficient to press .them downward and raise the printing bars. As theform passes under the paper cylinder, the plates, C, C, are `presseddown by the cylinder and the frame, D, D, is raised until theprinting-bars reachthe position, shown in Fig. '5, one face of each ofthe printing-bars being brought to the level of the type of the form andthereby pressed against the paper on the cylinder which thus receives animpression from the type of the printingbars in the color furnished toAthem by the inking-pad, X. Assoon as the pressure of the cylinder uponthe plates, C, C, is removed, they rise again underl the influence ofthe spring, S, thereby bringing a fresh face of each of theprinting-bars into contact with the inking-pad. As this operation isrepeated the faces of the printing-bars are successively inked andpressed against the paper on th-e cylinder, an impression beingprintedupon. the paper at each operation.

It will be observed that in the device hereinbefore described, each ofthe printing bars is rotated in each vertical movement of the frame D,D', whether downward or upward. This is a necessary feature of theoperation of the device if the printing bars be prisms of uneven numbersof faces, since in that case no two faces of any bar can be parallel,and the faces can only be presented successively to the horizontalinking-pads, and the horizontal plane of the form, by partial rotationof each bar in each of its vertical movements. I greatly prefer to usebars of triangular cross-section forthe reason that the faces of suchtriangular bars may be made of such width as to practically form anunbroken printing surface while still leaving sufficient space for thebars to rotate freely without touching each other. This being so, thestep by step rotation of each of the bars at each vertical movement ofthe printing frame is an important feature of the operation of thedevice, and I desire to .claim the construction by whichI secure thisfeature Ofoperation, as distinguished from that in which printing barsare partiallyrotated by the movement of'their support in one directionbut are not rotated in the reverse movement thereof.
